質問 # 92
As shown in the figure, which of the following ports will be in blocking state?
- A. G0/0/1 of SWC
- B. G0/0/3 of SWA
- C. G0/0/2 of SWC
- D. G0/0/3 of SWB
正解：D
解説：
Detailed Explanation:In a Spanning Tree Protocol (STP) environment, the root bridge is selected based on the bridge ID. Here, SWA has the lowest bridge ID (4096:0001-0203-04AA), making it the root bridge. For each network segment, STP elects one designated port to forward traffic, and all other ports in that segment will be blocked to prevent loops.
Following the STP rules:
* SWA is the root bridge, so all of its ports (G0/0/2 and G0/0/3) will be designated ports.
* Each non-root switch (SWB and SWC) selects one root port, which is the port with the lowest path cost to the root bridge (SWA).
* SWB's G0/0/3 will have a higher path cost when compared with G0/0/1 (if assuming equal link costs), thus making G0/0/1 the root port on SWB.
* SWB will then block its G0/0/3 port to prevent a loop, as SWA's G0/0/3 is already the designated port for that link.
Hence, G0/0/3 of SWB will be in the blocking state to maintain a loop-free topology
質問 # 93
How many more bytes are the packets using MPLS label double-layer nesting technology than the original IP packets ()
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
質問 # 94
Static NAT can only implement one-to-one mapping between private and public addresses.
- A. FALSE
- B. TRUE
正解：A
解説：
Comprehensive Explanation: Static NAT (Network Address Translation) can implement both one-to-one and many-to-one mappings. In a one-to-one mapping, each private IP address is mapped to a unique public IP address. However, in some cases, static NAT can be configured to map multiple private addresses to a single public address, particularly for services that do not require incoming connections. This flexibility allows for more efficient use of limited public IP address space.
質問 # 95

質問 # 101
Which of the following MAC addresses cannot be used as the MAC address of host network adapters?
- A. 02-03-04-05-06-07

- C. 0002-0304-05-06
- D. 03-04-05-06-07-08
正解：B
解説：
Detailed Explanation:MAC addresses that start with the first octet having the least significant bit (LSB) of the first byte set to 1 (such as 01-02-03-04-05-06) are multicast MAC addresses, and these cannot be assigned to a host's network interface card (NIC). Only unicast MAC addresses can be assigned to hosts.

10.2.2.1 00e0-fc99-9999 Eth-Trunk 1
192.168.20.1 00e0-fc99-9999 vlan100
10.0.0.1 00e0-fc99-9999 vlan200
- A. False
- B. True
正解：A
質問 # 105
In the following figure, all links are Ethernet links, and all interfaces on the routers are running OSPF. Given this, how many DRs will be elected on this network?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
In OSPF networks, a DR (Designated Router) is elected for each broadcast domain, such as each Ethernet segment. Given the topology where there are multiple Ethernet segments, a DR will be elected in each segment, resulting in three DRs based on the configuration and network design.
質問 # 106
Which of the following statements is true about root bridge election in STP?
- A. If the bridge priorities are the same, the device with the largest number of ports becomes the root bridge.
- B. If the bridge priorities of devices are the same, the device with the largest MAC address becomes the root bridge.
- C. The device with the largest bridge priority becomes the root bridge.
- D. The device with the smallest bridge priority becomes the root bridge.
正解：D
解説：
Detailed Explanation: In STP, the root bridge is elected based on the lowest bridge priority. If there is a tie in bridge priority, the device with the lowest MAC address is selected as the root bridge. This process ensures a stable, predictable root bridge selection in the network.
質問 # 107
On the network shown in the figure, Host A and Host B cannot communicate with each other.
- A. FALSE
- B. TRUE
正解：B
解説：
Comprehensive Explanation: Host A and Host B cannot communicate because they are in different subnets.
Host A's IP address is 10.0.12.1/30, while Host B's IP address is 10.0.12.5/24. Since they are in different subnet ranges and there is no router in the diagram to perform inter-subnet routing, direct communication between them is not possible without a router to route traffic between the different subnets.
質問 # 108
Refer to the following configuration of an interface on a switch. What is the PVID of the interface?
interface GigabitEthernet0/0/1
port hybrid tagged vlan 2 to 3 100
port hybrid untagged vlan 4 6
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
The PVID (Port VLAN ID) for a hybrid port refers to the VLAN that is assigned to untagged traffic. In this case, VLAN 4 is specified as untagged, making it the PVID for this interface. Traffic received without a VLAN tag is associated with VLAN 4 upon entering the switch.
質問 # 109
The switch G0/0/1 port configuration information is shown in the figure. Which VLAN data frame does the switch forward without VLANTAG? ? () (Single-choice question)
- A. 0

MAC-BG0/0/2
MAC-CG0/0/3 - B. MAC-AG0/0/1
MAC-BG0/0/2
MAC-CG0/0/1 - C. MAC-A--GO/0/1
MAC-B--G0/0/1
MAC-C--GO/0/3 - D. MAC-A--GO/0/1
MAC-B-G0/0/2
MAC-C-GO/0/3
正解：D
質問 # 111
Which extension headers are supported by IPv6 packets?
- A. Fragment extension header
- B. VLAN extension header
- C. Destination Options header
- D. Hop-by-Hop Options header
正解：A、C、D
解説：
Comprehensive and Detailed Explanation:
* IPv6 supports several extension headers:# Fragment Extension Header # Handles packet fragmentation.
# Destination Options Header # Stores information for destination nodes.# Hop-by-Hop Options Header
# Used for router-specific instructions.
# Incorrect Option:
* VLAN extension header does not exist in IPv6. VLAN tagging is handled at Layer 2 (Ethernet).
# Reference: HCIA-Datacom Network Principles Guide - IPv6 Packet Structure
質問 # 112
The load balancing modes at both ends of an Eth-Trunk can be different.
- A. FALSE
- B. TRUE
正解：B
解説：
Comprehensive Explanation: It is possible for the load balancing modes at both ends of an Eth-Trunk (Ethernet Trunk) to be different, as long as the devices at both ends support the different modes. Load balancing modes control how traffic is distributed across multiple links in the trunk. Although the modes may differ, they must be compatible in terms of ensuring that traffic is appropriately handled across the multiple physical interfaces bundled in the trunk.
